In (continental) Europe we use "the long system". It annoys the hell out of me when I see bad translation of these big numbers. For example, when it says world population is 7 billion. To me (and everybody else in my country) it means 7 000 000 000 000, not 7 000 000 000. Once I saw quadrillion translated as quadrillion, when I should have been translated as a billiard. Though incomprehensible, the difference is enormous.
